Linearly Constrained Smoothing Group Sparsity Solvers in Off-grid Model
Cheng-Yu Hung, Mostafa Kaveh
In compressed sensing, the sensing matrix is assumed perfectly known. However, there exists perturbation in the sensing matrix in reality due to sensor offsets or noise disturbance…

Joint Block Low Rank and Sparse Matrix Recovery in Array Self-Calibration Off-Grid DoA Estimation
Cheng-Yu Hung, Mostafa Kaveh
This letter addresses the estimation of directions-of-arrival (DoA) by a sensor array using a sparse model in the presence of array calibration errors and off-grid directions. The…
